Sending Signals

Scientists have genetically engineered immune cells cable of delivering anticancer-signals to organs where cancer may spread. Immunotherapy is a pillar of cancer treatment; strengthening the patient’s immune system and then directing the bolstered immune system to attack tumors. In this effort, Adoptive Cell Transfer is proving successful. With this immunotherapy treatment a patient’s immune cells are collected, engineered for the patient’s specific cancer and then reintroduced into the patient to treat their cancer. There are numerous types of Adoptive Cell Transfer and the most prominent one is called CAR T Cell Therapy.

Cancer Fighting Immune Cells

In 2010 two blood cancer patients received an experimental immunotherapy, and their disease went into remission. The cancer fighting immune cells used in the treatment were still circulating in their bodies,  ten years after the experimental dosing. It indicates that the treatment can be long lasting. Doug Olsen, a native Californian, was one of the patients, “From a patient’s viewpoint, when you are told you are pretty much out of options, the important thing is always to maintain hope. And certainly, I hoped this was going to work”, said Doug Olsen at a news briefing. The CAR T Cell Therapy used the patients’ genetically engineered immune cells to track down and destroy cells that cause cancer.
